[LLVMdev] Chain and glue operands should occur at end of operand list
...Emitter::AddOperand. I
am writing a back end for CortexM0 (for self teaching purposes), I am
working on LDR with immediate offset instruction.
In the ARM backend,
if the offset is 0, the following code is executed by the function
ARMDAGToDAGISel::SelectThumbAddrModeImm5S
Base =
N.getOperand(0);
OffImm = CurDAG->getTargetConstant(0, MVT::i32);
If I
do a similar thing in my backend, I get this assertion message. I found
out that if I execute the code below, the problem disappear.
Base =
N;
OffImm = CurDAG->getTargetConstant(0,
TM.getTargetLowering()->getPointerTy());
Only the change...
